In 2017-2018, startups like MedRec and BurstIQ began applying blockchain to patient data management and secure medical records
MedRac was developed by MIT researchers, including John Halamka and Ariel Ekblaw.

MedRec used Ethereum to enable patient controlled medical records, integrating with hospital databases and incentivizing researchers to validate transactions for data access.

The shift from research to commercial product development is crucial for blockchain initiatives like MedRec to succeed in the healthcare industry. Overcoming scalability issues and gaining hospital adoption are key challenges that require strategic planning and industry collaboration. Hopefully, lessons learned from MedRec will inform future blockchain projects in healthcare.
